One thing to keep in mind is the application you want to use the buzzer for. An internal oscillator (D.C.) version will produce a set tone (3100hz ?) and would be used in a smoke detector or similar application where you want a noise to alert you of an error condition.
The externally driven ones will allow you to play a tune like a musical greeting card and allow you to produce the effect of different notes. If you are driving the buzzer from a logic level signal that goes from zero to some positive voltage then the zero-peak types are what you want. If you have a signal that is symmetrical around zero then the peak-peak is the way to go.

Thank you Arthur. In my application, the buzzer is just going to provide an alert that it's time to open the oven door, or remove the board from the hot plate, and do it right now. So a continuous, obnoxious tone will work fine.
By the way, I see that your reply was your post #442, which I think means it is not only the answer to the buzzer question, but also the answer to life, the universe, and everything. Thank you so much.
